Know those little aches and pains you feel in the morning? You could do something right now to keep them from getting worse when you're older.

Just jump to it. Okay, you don’t have to literally jump. But do be active. People who pick up their feet and commit to regular aerobic exercise have much less muscle and joint pain as they age.

How Much Less?
A 14-year study that followed a healthy over-60 crowd found that consistent exercise -- be it running, biking, swimming, dancing, or brisk walking -- led to as much as 25 percent less musculoskeletal pain down the road. Yes, even with the high-impact runners. Researchers aren't sure why, but they suspect that exercise’s endorphin release may play a role. (Find out how to turn exercise into an endorphin-rich mental pick-me-up, too.)

Looking Ahead
Less pain when you're older means a more active and independent life. Here are a few other ways to lower your risk of chronic future aches:

• Hit the mat. Yoga boosts endorphins and improves flexibility and joint-supporting strength. Try this simple yoga stretch.
• Cross-train. Mixing up your activities helps keep your back in good shape. Plus, you'll get these health benefits.
• Have a cup or two . . . of green tea. Here's how it can help stave off knee pain.
